Fortnite XP Glitch Allows Easy Challenge Completion

A Fortnite glitch affecting experience is allowing players to complete all the challenges in the game quickly and easily by heading into Creative mode, making for a massive windfall of XP.
Fortnite YouTuber Glitch King posted a video Saturday explaining the glitch, which he claims can provide unlimited experience. Glitch King's video states the exploit requires two players.

The two players load into a Creative match, then set up a glitched Tilted Taxis limited-time mode match with the Creative code 7486-7787-8934. Once you've queued for matchmaking and found a match, you'll have no enemies and no time limit to complete your challenges.
Epic Games will likely fix this bug as quickly as possible, though the developer has yet to acknowledge it. It's possible the developer will seek punitive action against players who abuse the exploit.
